In view of the force problem in process first shoveling method underground forklift, I used EDEM software to complete numerical simulation calculation method, generate ore stacks, imported bucket model, set action, and completed shovel simulation. Which pairs consider distribution ores. Summarize provide a certain reference for subsequent research.

A layered fertilizer shovel is designed to achieve double layer fertilization in response the current problem of large efficiency loss one-time banding application. The key structural parameters were and working speed V, distance L1 between discharging pipe point-applied device L2 distribution plate determined as main factors affecting h. quadratic regression model indicators was established by...

The loss rate is an important index to evaluate the harvesting performance of white radish. To reduce rate, it necessary analyze pulling dynamic characteristics radish and then optimize structure operating parameters device. In this paper, according growth in field, discrete element method (DEM) was used simulate process. force calculated using Edinburgh elasto-plastic adhesion model (EEPA), ef...

The limit state criteria for a mining shovel mechanical equipment that contains the faults of rotor imbalance-type are studied in article. On bases statistical analysis failures, it is demonstrated imbalance prevailing reason their accident-caused failures. three-year monitoring supporting elements vibrating activity vibratory norms electrical rotors take into account service condition substant...
